| 3 | Running VPP |
| 4 | =========== |
| 5 | |
| 6 | Using the files we create in :ref`settingupenvironment` we will now start and |
| 7 | run VPP. |
| 8 | |
| 9 | VPP runs in userspace. In a production environment you will often run it |
| 10 | with DPDK to connect to real NICs or vhost to connect to VMs. In those |
| 11 | circumstances you usually run a single instance of VPP. |
| 12 | |
| 13 | For purposes of this tutorial, it is going to be extremely useful to run |
| 14 | multiple instances of VPP, and connect them to each other to form a |
| 15 | topology. Fortunately, VPP supports this. |
| 16 | |
| 17 | |
| 18 | Using the files we created in setup we will start VPP. |
| 19 | |
| 20 | .. code-block:: console |
| 21 | |
| 22 | $ sudo /usr/bin/vpp -c startup1.conf |

| 30 | If VPP does not start you can try adding **nodaemon** to the startup.conf file in the |
| 31 | **unix** section. This should provide more information in the output. |
| 32 | |
| 33 | startup.conf example with nodaemon: |
| 34 | |
| 35 | .. code-block:: console |
| 36 | |
| 37 | unix {nodaemon cli-listen /run/vpp/cli-vpp1.sock} |
| 38 | api-segment { prefix vpp1 } |
| 39 | plugins { plugin dpdk_plugin.so { disable } } |
| 40 | |
| 41 | The command **vppctl** will launch a VPP shell with which you can run |
| 42 | VPP commands interactively. |
| 43 | |
| 44 | We should now be able to execute the VPP shell and show the version. |
| 45 | |
| 46 | .. code-block:: console |
| 47 | |
| 48 | $ sudo vppctl -s /run/vpp/cli-vpp1.sock |

| 56 | vpp# |
| 57 | |
| 58 | .. note:: |
| 59 | |
| 60 | Use ctrl-d or q to exit from the VPP shell. |
| 61 | |
| 62 | If you are going to run several instances of VPP this way be sure to kill them |
| 63 | when you are finished. |
| 64 | |
| 65 | You can use something like the following: |
| 66 | |
| 67 | .. code-block:: console |
| 68 | |
| 69 | $ ps -eaf | grep vpp |
| 70 | root 2067 1 2 05:12 ? 00:00:00 /usr/bin/vpp -c startup1.conf |
| 71 | vagrant 2070 903 0 05:12 pts/0 00:00:00 grep --color=auto vpp |
| 72 | $ kill -9 2067 |
| 73 | $ ps -eaf | grep vpp |
| 74 | vagrant 2074 903 0 05:13 pts/0 00:00:00 grep --color=auto vpp |
